IMPROVEMENT IN' FANNINGj-MILLS.

MOM-

The Schedule referred to in these Letters Patent and making part of thesame To all whom it may concern:

Be it known that 1,HARR1S0NA Oc-Bonn, of Richmond, inthe county of Wayneand State of Indiana, have invented new and useful Improvements inFanning-Mills; andI hereby declare the following to be a full and cleardescription of the same, sufficient to enable others skilled in the artsto which my improve. ment belongs to fully understand, construct, anduse the same, reference being had toA the accompanying drawing makingpart of this specification, in which- Figure l is a perspective View ofmy machine; Figure 2 is a top view of the shaker and adjoining parts.

Similar letters of reference refer to correspomling parts in thediierent igures.`

The nature of my invention consists in the use of al double shaker for atanning-mill, and of horizontal hars or rods'and guides for hanging theshoe ota fanningvmill, so that the motion given to it by theshakingdevices will be a firm, steady, smooth, horizontal motion.

K M N Pis a doubleshaker, for givinga light or heavy shake, which isalso a'regular rm shake, to the shoe of a tanning-mill over its entirelength, and for regulating the shake of' the shoe, so that either end ofthe shoe can be made to vibrate more orless, with- `out changing thelengtlrof the vibrations ofthe other end of the shoe. p

L L- are boxes for holding the shaker in position.

A A is a. cross-frame, which supports the various parts lot' themachine. v

B arc the cross-braces. r

G is the fan-case, through which passes Aa shaft, to which wings areattached, all made in the usual'manner.

G is a pinion-wheel, ou the end of the fan-shaft, for giving motion tothe same.

F'is the master-wheel, to which the handle O is attached.

'I T are sides forming part of the drum; also act as a support for therod X', anda-s ends to the hop- .per D.

. the shoe.

N is an arm, forming part ot' the bell-crank M, connected with the sameby the longer rod H into the pinion G.

On. the bottom of the shoe U is placed wire-cloth, finer than thatonscreen V, to allow of two or more separations at the same time; agreat variety of grain Iand seeds may be cleaned and separated on 'thema chine Vby having suitable screens.

Y is a spout, the bottom of'whieh is inclined downward to onevside,which conveys the large tine wheat to one side of the machine. By itsside is another spout into which the smaller wheat falls, by reason ofthe lower screen being-a little shorter, and is sloped in the oppositedirection to the other side of the machine, Where the wheat is carriedand falls oli.

X X are rods that support the shoe; the rod X passes through the frame,and through holes in plate a, on the 'sides of the shoe. The holesthrough the plate are enough below the bottom of the shoe to prevent itsrubbing. The screen-rod X' passes through the fan-case 'I and shoe U,Aabove the Ion g screens and below the short one, 'and through platesfastened on the sides of the' shoe.

To clean wheat it is placed in the hopper D, and,` i

motion being given to the machine, the board E is slightly drawn out.The wheat and all impurities fall vdown `on to the screen W, which takesout all large particles. The wheat falls through the screen'W onto achessboard,'and from there onto the upper end of the long screen, orfrom the upper screen directly onto the long screen when the chess-hoardis removed. iVhile failing the blast ot' air from the fan strikes it,and ,blows out the iight chaify particles; the screen V retains thelarge tine grains or seed-wheat which passes down the screen, and fallsinto the spout Y, and from it into any convenient vessel.

The smaller grains of wheat, chess, cockle, and other small impurities,fall through screen V onto the lower screen, heretofore spoken of, whichagain screens it, and retainsv the small grains oi' wheat, suitable formarket, and passes them down the screen and linto the other spout, fromwhich they fall ou the other side, in any vessel suitable for thepurpose, while the chess, cockie, Vsmall foul seeds, sand, dirt, andother impurities,y fall through the screens onto the tioor.

- Having described my improvement in fanninganills,

What I claim as new, and wish to secure by Letters Patent, is`

The shoe U, provided with plates a' a and ears S S, the supporting-rodsX X', operating-rods H I R, and bellcrank K M Nl P, when said parts' areconstructed, combined, and arranged to ope-rate substantiallyasfdescribed, and for the purposes-set forth.
